METHOD FOR PROCESSING FLUOROCARBON RAW AND QUENCHING PROBE USED IN IT Russian patent published in 2005 - IPC

FIELD: chemical technology.

SUBSTANCE: invention relates to processing liquid fluorocarbon raw to valuable fluorine-containing gaseous products and to quenching probe method used (abrupt cooling). Method for treatment of fluorocarbon raw involves generation of high temperature in the zone of arc between at least one cathode and at least one anode, generation of high temperature in the zone by electric arc and gaseous thermal plasma with tail torch. Chemical active thermal mixture with tail torch of thermal plasma is formed from fluorocarbon raw that comprises at least one fluorocarbon compound. Fluorocarbon compound dissociates and forms at least one fluorocarbon precursor or its chemically active species having less carbon atoms as compared with fluorocarbon compound. Then chemically active thermal mixture is cooled to form fluorocarbon from the precursor or chemically active species of fluorocarbon product. Preferably, raw has a liquid form and represents fluorocarbon by-side products comprising two or more fluorocarbon compounds being one of them represents the main product containing less five carbon atom usually. Preferably, raw is added to the tail torch of plasma and plasma is fed to the high temperature zone. The self-cleansing quenching probe comprises external cylindrical component assembled on reactor and having the central channel for cooling hot gas or chemically active thermal mixture. The internal cylindrical component is installed with a gap inside of the external component and used for cooling hot gas or chemically active thermal mixture that pass through peripheral gap between components. Method provides reducing exploitation consumptions, possibility for regulating parameters of the process and the composition of feeding mixture and the yield of end products.

EFFECT: improved method for processing.
